Former Who guitarist Pete Townshend is mounting an American

mini-tour around his performance at the Aug. 15 "A Day in the Garden" festival in Bethel,

N.Y.

During the tour -- which will also include appearances on the "Late Night with David

Letterman" television show (Thursday) and at the Harborlights Pavilion in Boston

(Friday) -- the veteran rocker will play a Sunday benefit show at the House of Blues in

Chicago, for the local Maryville Academy, a residential facility for abused and

abandoned boys and girls.

In 1995, Townshend played a similar Maryville Academy benefit, during which he was

joined by Pearl Jam singer Eddie Vedder.
